OBJECTIVE The goal of this study was to develop and validate a short form of the Childhood Trauma Questionnaire (the CTQ-SF) as a screening measure for maltreatment histories in both clinical and nonreferred groups. METHOD Exploratory and confirmatory factor analyses of the 70 original CTQ items were used to create a 28-item version of the scale (25(More)
A new stroke volume equation for thoracic electrical bioimpedance is proposed. This empirically derived formula differs from previous equations in that: the thoracic volume conductor is modeled geometrically as a frustum (truncated cone), rather than a cylinder; the specific resistivity of blood, rho, is appropriately eliminated as an independent variable;(More)
To study the psychometric properties of the Childhood Trauma Questionnaire-Short Form (CTQ-SF), we determined its dimensional structure, measurement invariance across presence of emotional disorders, the association of the CTQ-SF with an analogous interview-based measure (CTI) across presence of emotional disorders, and the incremental value of combining(More)
Borderline Personality Disorder (BPD) is associated with interpersonal problems, such as intense, unstable relationships and fears of abandonment. It has been hypothesized that deficits in social cognitive capacities explain these difficulties. One important aspect of social cognition is theory of mind (ToM)-the capacity to infer others' mental state. We(More)
The study's goal was to determine if cardiac output (CO), obtained by impedance cardiography (ICG), would be improved by a new equation N, implementing a square root transformation for dZ/dtmax/Z0, and a variable magnitude, mass-based volume conductor Vc. Pulmonary artery catheterisation was performed on 106 cardiac surgery patients pre-operatively.(More)
The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a 28-item retrospective self-report questionnaire designed to assess five dimensions of childhoodmaltreatment: (1) Physical Abuse, (2) Emotional Abuse, (3) Sexual Abuse, (4) Physical Neglect, and (5) Emotional Neglect. A March 2009 MEDLINE search found 141 references to the CTQ-SF, whereas no other(More)
This study investigated the relationship between five forms of childhood maltreatment (sexual, physical and emotional abuse, emotional and physical neglect) and 10 personality disorders (PDs). PDs were assessed by means of SCID II, and childhood maltreatment was retrospectively measured with the Interview for Traumatic Events in Childhood. Both PDs and(More)
Thoracic electrical bioimpedance (TEB) is a harmless, noninvasive, user-friendly technology with wide patient acceptance. Stroke volume (SV) determination is important because it helps to define oxygen transport. Measurement of SV by TEB is rooted in concrete, basic electrical theory, as well as in theoretical models of electrical behavior of the human(More)
Thoracic electrical bioimpedance (TEB) is a noninvasive method for the estimation of left ventricular stroke volume (SV). Objections to TEB in the past have included systematic overestimation of SV and cardiac output in normals, poor correlation in absolute terms with standard cardiac output reference techniques, motion and ventilation artifacts which(More)
BACKGROUND A number of practice guidelines and recommendations call for the assessment of childhood abuse in adult medical patients, but none specifies how best to do this. The objective of this study was to use evidence from 2 community-based population samples to evaluate abuse-screening questions that are often asked in medical clinics and to identify a(More)
